An inductance device (14a) comprises a magnetic core (15a), a coil (17,18), a conductor (23a) and a dielectric member (22). The coil is made of turns of insulated conductive wire (17,18). The conductor (23a) is distinct from the coil (17,18) and is insulated from the magnetic core (15a). The dielectric member (22) is disposed between the conductor (23a) and the coil (17,18). The dielectric member (22), the conductor (23a) and the coil (17,18) constitute a capacitor. The inductance device (14a) is used in, for example, a filter device or a noise filter.
